摘 要: | 实际应用中需要提取低截获概率信号的方位信息,而低截获概率信号往往淹没在干扰信号中。文中应用谱相关理论对淹没在干扰信号中的低截获概率信号进行测向,模拟结果表明,将谱相关应用到阵列测向后,能比M U SIC方法更好地完成对低截获概率信号的测向。

Abstract: | The information of low probability interception (LPI) signals is useful in practice,but LPI signals are often hided or put in jammer,which show more difficulty in direction-finding.This paper exploits the characters of signals and uses spectral correlation theory in direction-finding of LPI signals in jammer.The simulation results show that the combination of array direction-finding and spectral correlation theory can get better results than the method of MUSIC in direction-finding of LPI signals. |
